Molecular fossils are preserved organic molecules derived from ancient organisms, providing insights into past environments and evolution. These molecular remnants can include lipids, proteins, and nucleic acids found in rocks, sediments, or other geological materials. They are used by scientists to study the history of life on Earth and understand biological and ecological changes over time.

What is the definition for fossil?
Fossils are the preserved remains or impressions of living organisms that lived in the past. They can be found in rocks or sediments and provide important information about the history of life on Earth.
Definition of pseudo fossil?
Pseudo fossils are geological formations that appear to be fossils but are actually created through non-biological processes such as mineral deposits or erosion. They lack the organic matter or structure typical of true fossils.
Why wouldn't you want to be a molecular paleontologist?
Personally, I wouldn't want to be one because I am more fascinated by language and philosophy than by cells and fossils... but it definitely does seem like an interesting thing to do, if that is where your passion is.
What was the preserved remains of ancient organisms called?

What is fossil form a specific time period?

How is the term molecular properly defined?

Are preserved animal tracks index fossils?
According to the definition of "Index Fossils" the answer is no. The definition of an "Index Fossil" is - remains of an organism that lived in a particular geological age. While the track itself may indicate the age of sediment, it is not a fossil.

What does paleonthrologist mean?
The definition of a paleontologist is a person who studies fossils. These are people who try to analyze ancient life.

Molecular hydrogen is a diatomic element containing two covalently bonded hydrogen atoms with the chemical formula H2. Molecular hydrogen is colorless and odorless.
How are fossils used?
Fossils are used by scientists to answer questions about species and maybe even dinosaurs. They use the fossils and run tests by using there DNA and seeing their molecular structure and running it by other animals for similarity's.
